Rosenort originated south and east of the town of Tiegenhof through the immigration of Dutch Mennonites, to whom the banking firm of Hans Simon and Steffen Loysen in 1562 granted land near Danzig to be made arable. Until 1772 Rosenort was located in what was known as Royal Prussia (also known as Polish Prussia) in the Kingdom of Poland. The First Partition of Poland in 1772 resulted in the creation of a new province in 1773, called West Prussia, in which Rosenort was located. Rosenort was situated in the district (Kreis) of Elbing until the establishment of the Free City of Danzig in 1920. The village came under the control of Nazi Germany during World War II until February 1945, when it was occupied by Soviet forces and returned to Poland. In 2012 Rosenort (now Suchowo) was a settlement in the administrative district of Gmina Nowy Dwór Gdański, within Nowy Dwór Gdański County, Pomeranian Voivodeship.
